It looks like the Union City, MI tornado will stay as high end EF-3. They did bring in a QRT to help with determining the rating. Just not enough convincing evidence to go with an EF-4 rating.

Survey Summary:
The most intense and deadly tornado of the cyclic tornadic
supercell touched down in northwest Branch county, northwest of
Union Lake between Blossom Rd and Mendon Rd. This tornado was
well photographed from multiple angles, and it quickly turned
into a multi-vortex wedge. After destroying a pole barn and
damaging a residence, the tornado deposited a 500 gallon propane
tank in a field. Drone footage also showed ground scouring in the
same field. The tornado continued northeast and caused the most
widespread and intense damage along Prairie Rose Ln. Every
residence along this stretch was either heavily damaged or
completely destroyed. Tragically, three individuals lost their
lives here when their manufactured homes were lofted and tossed.
One of these trailers was well anchored and tossed approximately
100 yards, badly twisting the frame. Numerous vehicles were also
tossed in this area. The maximum peak intensity of 160 mph was
estimated to be at the corner of Tuttle Rd and Prairie Rose Ln.
This 2 story block home was completely destroyed. Construction
quality and older building codes of all homes in this area
contributed to their failure and precluded the survey team from
being able to rate higher than an EF-3. The tornado continued off
to the northeast into Union City producing EF-1 to EF2 damage
along the way before dissipating at the Branch/Calhoun county
line. Special thanks to the various subject matter experts on the
Quick Response Team that helped NWS Northern Indiana determine
this tornado`s intensity.
I can buy that there may be more important variables (summer precip, dry winds) than snowpack, but saying "there's little to no correlation with spring snowpack and the following wildfire season" is questionable because you're not controlling for confounding variables with your examples. An above-average snowpack could be impacted by a very warm summer and a below-average snowpack could be less impacted by a mild summer. Oregon is in a worse position for fire season with a minimal snowpack than if they had an above-average snowpack, are you disagreeing with that? If not, then it doesn't seem absurd to root for a good snowpack to improve our odds re: fire season.
